An image display system is provided and includes: at least one first projection unit, configured to project rays of N images on a first plane, so that the rays of the N images are projected on N first regions of the first plane, where the N images are images of a target object photographed based on N angles, and N≥2; and at least one first refraction unit, configured on the first plane, and configured to perform refraction processing on the rays of the images projected on the first regions, so that the rays of the N images are collected on a common display region. In this way, presentation of a three-dimensional image can adapt to a human eye viewing habit.
